模糊條帶
英文
faint band-
The milky way will look like a hazy, cloud-like, irregular band across the sky.
銀河看來就象一條橫在天空的、模糊的、不規則的、雲霧狀的帶子。And the resemblance is pointed out between continuous wavelet transform ( cwt ) and waf. in the course of computing waf, the scaling replica is very important. based on the properties of cwt, three approaches have been proposed for the scaling of a wavelet that has no analytic form
詳細闡述了寬帶信號及系統的三個條件、寬帶系統的回波模型和寬帶模糊度函數的概念,指出了連續小波變換( cwt )與寬帶模糊度函數的驚人相似之處。Absorb spectrum : under the strong glint light, occasionally it is thus clear that wait to 432 納 rices and 420 納 rices absorption of the weak blue area to take in 2, sometimes in 460 納 rices it is thus clear that the unclear absorption takes
吸收光譜:在強的反射光下,偶爾可見兩條中等至微弱的藍區432納米和420納米吸收帶,有時在460納米處可見模糊不清的吸收帶。At last, a method to fuzzy linear programming with fuzzy constraints is presented, and it is illustrated that the conclusion of this paper are correct and this algorithm is more simplex algorithm by numerical example
最後給出了約束條件帶有模糊性的模糊線性規劃的相應解法,並用實例說明了本文結論的正確性與演算法的簡捷性。At the same time, the " stop - hop - stop " approximation is no longer valid in sas due to the low speed of sound. the receiver has unavoidable movement, when echoes get to receiver from different distances. in order to overcome the problem, an image forming algorithm of multi - aperture sas is presented in the thesis, which is suitable for the case of non - " stop - hop - stop "
為了解決測距、測速模糊問題, sas通常採用多子陣技術,而且由於sas 「停?走?停」假設往往不再有效,即測繪帶內不同距離回波到達基陣時,基陣存在不可忽略的運動,所以論文提出了一種「停?走?停」假設不成立條件下的多子陣合成孔徑聲納逐點成像演算法以得到相位保真度更高的復圖像。One new method that the uwb signal can be received ambiguously has been presented in this dissertation. furthermore, the sampling lfm signal becomes two sine signals with different frequencies based on two different delay processes. based on fft and remainder algorithm, the modulation rate and initial frequency of sub - sampling lfm signal are estimated precisely and unambiguously in negative snr
該方法通過在數字域對信號進行兩路不同的延時和余數定理實現欠采樣條件下超寬帶線性調頻信號的調制斜率和初始頻率的無模糊估計,在不降低參數估計精度的前提下,解決了欠采樣方法引起硬體復雜度增加的問題。In addition, based on fft and remainder algorithm, the modulation rate and initial frequency of sub - sampling uwb lfm signal are estimated unambiguously in negative snr
該方法通過fft和余數定理解頻率模糊,解決了負信噪比條件下超寬帶線性調頻信號調制斜率和初始頻率的估計問題。分享友人
